Document Type and Number:
WIPO Patent Application WO/2022/121506
Kind Code:
A1
Abstract:
Disclosed is a rear-mounted direct-drive type rotary mechanical arm, comprising a working arm, a power box mounted at the front end of the working arm, and a hydraulic rotary connection unit mounted at the rear end of the working arm; the hydraulic rotary connection unit is located between the working arm and a connection frame; a working shaft is mounted on the power box in a rotatable connection manner; and an output shaft of the hydraulic rotary connection unit is connected to the working shaft by means of a transmission mechanism to drive the working shaft to rotate. In the present invention, a driving device is configured to be rear-mounted and a front-rear connection function is added; power is transmitted by means of the transmission mechanism to drive the working shaft to rotate, so that the driving device can be far away from a high-temperature and high-corrosion region, improving the stability of the device; furthermore, the driving device selects a hydraulic rotary connection unit and is integrated with the working arm, so that compared with conventional motors and speed reducers, the driving device has a simple structure, small volume and light weight and can move more flexibly.
